Low-Noise Preamplifier For Fm Receivers

to provide new mounting holes on the PCB if you intend to use Type N or F sockets instead of BNC. Mount a suitable clamp to the box to enable at- taching this near, or onto, the dish aerial stand, if this is the most favourable lo- cation for the splitter considering the lengths of the downlead cables. Provide lettering on the lid to rule out any likelihood of erroneous connections. Now proceed with the completion of the printed circuit board shown in Fig. 2. Less experienced constructors should note that all parts, with the exception of the 3 sockets, are fitted direct onto the track side of the board. The leads of C7, RI and the 3 inductors should be kept as short as possible. The MMIC is seated in a 04 mm hole, and its 4 leads are soldered straight onto the relevant copper areas. All capacitors, with the exception of tantalum bead type C7, are surface mount devices, secured in place by fast soldering with a low- power iron. The same goes for divider resistors R2 and R3.
